Method of tail beam posture prediction of top coal caving hydraulic support based on LSTM [PDF]
Fully mechanized caving is the main mining method for extra-thick coal seams in my country. The control accuracy of the caving actuator depends largely on the data feedback of the tail beam posture.

A study on the mechanism and control technology of strong mine pressure in parallel coal pillar and hard roof mining [PDF]
In multi-seam mining, as mining ranges expand and depths increase, the strong ground pressure exerted on the lower coal-seam working faces (WFs) or roadways by coal pillars (CPs) and the hard roof between the interburdens becomes increasingly severe ...
